2039-2012《Metal material simple tension creep test method》In gauge length of having no progeny, smallest cross-section area of having no progeny are defined,
Wherein " when fracture sample carefully being alignd at room temperature and is ensured its axis on the same line on sample mark between away from
From " gauge length of having no progeny is defined as, " after sample fracture, sample fracture part carefully being alignd at room temperature so as to which axis is in same
The smallest cross-section area in parallel-segment determined when on one straight line " is defined as smallest cross-section area of having no progeny.From standard requirement not
Indigestibility, must ensure that its axis is measured on the same line in measurement process.Because gauge length of having no progeny, minimum of having no progeny
The accuracy of measurement of cross-sectional area will directly affect the accuracy of elongation percentage, the contraction percentage of area.
At present, the metering system of sample is still measured for laboratory technician's operation measurement instrument (such as micrometer), examination of having no progeny
Sample is placed in the iron block for be provided with V-groove and measures, or be placed in docked in the fixture of making after measure.But V-groove pair
It is unstable to be not easy to measurement because sample is likely to occur rotation after docking in the measurement of bar, while V-groove is to sheet coupon
Measurement does not have booster action.Related fixture is also that the sample of fracture is pre- near being docked again by certain mode
Tight mode, such method has no installation site for sample, because fracture sample is contacted with fixture for face, it is impossible to avoid sliding
It is dynamic, only carry out Control Assay in same axis by pretightning force or allow it to measure on V-groove, planar support platform, it is impossible to
The free degree of sample is entirely limited, be may still result in after sample docking not on the same axis.
